Milestones: https://github.com/open-mpi/ompi-release/milestones/v2.0.0
Master PR1817 - does this need to go to 2.0.0 or 2.0.1?
- Master PR that Pasha @ Mellanox says needs to go to v2.x
- need more info about reproducer of bug this fixes. Maybe UCX / Add procs non-default issue?
v2.x PR1246 - cherry pick of MPI_Request Multi-thread race condition. Hope to get in tonight.
Last week still waiting on:
- PR1237 on ompi-release - PR1794 and PR1795
- and Jenkin's failure on Mellanox cluster.
  - thread_test 1.1 - running overlap test. Not great, but good at finding bugs.
PR1821 - additional performance improvements for MPI_Waitsome() Not regression.
- George and Nathan need to look at.
If we get PR1821 and PR1246 in today and Jenkins runs okay:
- Roll RC4 tomorrow, and diagnose Mellanox issue.
- if we could release next Tuesday, that would be fantastic!

Andrew Lumsdaine, our primary faculty sponsor for Open MPI at Indiana University, is leaving IU.
- We have a bunch of Open MPI infrastructure hosted at IU (for free): the web site, MTT web reporter + database, ...etc. This infrastructure is now likely to go away within the next several months.
- There are many implications of such a move: cost, features, resources, timing, ...etc. We need to start talking about this as a community to decide: a) where to move OMPI's electronic infrastructure, and b) how to move it (there are complicated technical issues involved).
- Ralph, Howard, and I have been looking at alternatives over the past few days. We would like to present a few ideas / proposals to everyone.
- We have approximately 3 month deadline to find new home.
  - web services at IU (website, mailinglist archives, nightly tarballs).
  - MTT web + MYSQL needed also.
  - Building of nightly tarballs, and release tarballs.
  - Github automation - bots, other minor. Some is webbased, some is script / cron based.
  - Jenkins would go away.
- Jeff and Howard has Google doc, will transition to Wiki
- IU also is holder of legal docs. All data is now electronic, so should be okay to archive in a community space.
- Need to consider how to pay for services we were getting from IU for free.
  - Member dues, or Face to face registration costs or something.
Summer Meeting: (https://github.com/open-mpi/ompi/wiki/Summer-2016%2CTBD)
